VTM48MP010T135AA0 Übersicht
A VTM (Voltage Transformation Module) is a fixed-ratio DC-DC converter used in a Factorized Power Architecture (FPA), where a PRM (Pre-Regulation Module) provides a regulated intermediate voltage and a downstream VTM performs point-of-load current multiplication. Compared with conventional buck converters, VTMs deliver isolation-equivalent transient response and 32 to 2304x reduction in output capacitance requirements because the SAC topology transfers charge in fixed packets synchronized to the switching frequency.
Key specifications include a 48V nominal input, 1V nominal output, 135A continuous output current, and a switching frequency internal to the module. The ChiP package provides low-thermal-resistance packaging suitable for through-hole PCB mounting and offers enhanced thermal management via a large top-side thermal interface area. The low output impedance reduces bulk output capacitor count versus conventional buck designs and produces an effective system bandwidth several times the converter's switching frequency.
Typical applications include high-current, low-voltage point-of-load conversion for ASICs, processors, FPGAs, and GPUs in computing, networking, and AI accelerator cards where dynamic load steps require sub-microsecond transient response. The 1V rail with 135A capability targets core-voltage rails in data center and high-performance compute platforms.
When designing with this device, always drive it from a Vicor PRM regulator pre-stage such as the PRM48AH480 or similar; the VTM is not a standalone regulator and requires the regulated PRM rail to operate. Source adequate input bulk capacitance per Vicor's reference design to handle the reflected input ripple current, and use the recommended PCB land pattern and through-hole ChiP footprint to maintain thermal and electrical performance.

Typische Anwendungen
VTM48MP010T135AA0 ist geeignet für 6 Anwendungs: High-Performance Compute / AI Accelerator GPU Core Rail, Networking Switch ASIC Point-of-Load, FPGA Core Voltage for AI/ML Inference Cards, Server CPU/GPU VROne Card Power Delivery, 48V Direct Conversion Industrial Computing, Telecom Base Station Backhaul and Switch Fabric.
High-Performance Compute / AI Accelerator GPU Core Rail
The VTM48MP010T135AA0 delivers 1V at 135A continuous - the exact core-voltage envelope demanded by modern GPUs and AI accelerators in data-center compute cards. Placing the VTM directly at the load, after a 48V-input PRM pre-regulator on the motherboard, replaces the conventional 12V intermediate-bus-and-buck topology with a Factorized Power Architecture. The SAC ZCS/ZVS switching yields sub-microsecond transient response, so GPU transient events (where the core current can swing from 50A to 135A in under 1 µs) are absorbed without 200+ µF of bulk output capacitance. Typical companion parts: Vicor PRM48AH480T100A00 (pre-regulator upstream), and DSP or GPU rails powered directly from the 1V output. As a system trade-off, the VTM still requires the upstream PRM and adds one stage of conversion efficiency loss (~3-5%); the benefit is dramatically smaller output-cap count and tighter load-line regulation.

Networking Switch ASIC Point-of-Load
Large networking ASICs in core switches draw 100-150A at sub-1V core rails with very fast current steps when traffic bursts hit packet processing pipelines. The VTM48MP010T135AA0's 1V/135A output and SAC topology absorb transient di/dt that a conventional buck regulator cannot handle without hundreds of microfarads of ceramic. The ChiP-1323 through-hole package also supports direct thermal attachment to a heatsink or thermal interface, which is critical in dense multi-ASIC switch line-card designs. Source the VTM from a 48V intermediate bus supplied by a PRM, and place the VTM adjacent to the ASIC die on the same PCB. The reduction in capacitor count (up to 2304x vs conventional buck) frees PCB real estate for trace routing and additional switch ports.

FPGA Core Voltage for AI/ML Inference Cards
Modern FPGAs used in AI/ML inference workloads consume 60-140A at 0.85-1.0V core rails. The VTM48MP010T135AA0's 1V nominal output sits squarely in that window, and its 135A continuous rating handles the worst-case junction-temperature-corner case without current derating. Configure the upstream PRM at 48V nominal (or 24V input bus through a PRM24 variant), and add the VTM directly at the FPGA's power pins on a low-impedance PCB layer stack-up. The 2304x output-capacitance reduction translates to roughly 200-400x fewer MLCCs than a conventional buck, drastically reducing PCB cost and BOM count. Trade-off: the SAC switching frequency is fixed internally, so the design cannot tune the loop for a specific FPGA VID requirement - system designers compensate by sizing the output filter for the worst-case step load.

Server CPU/GPU VROne Card Power Delivery
Server-class CPU and GPU cards in HPC and hyperscale data centers require 1V rails at 100-200A with strict efficiency targets (>95% at full load). The VTM48MP010T135AA0 achieves 96-97% efficiency at nominal 48V input, helping meet PUE targets while still delivering 135A at 1V with a fixed 1:48 ratio. Deploy this VTM as part of a Vicor-factorized PSU chain: front-end AC-DC (e.g., VI Brick AC-DC) -> 48V intermediate bus -> PRM48AH -> VTM48MP010T135AA0 -> CPU/GPU core. The single-stage SAC reduces AC ripple at the load versus two-stage buck architectures. Trade-off: requires a Vicor PRM to operate - not a standalone regulator - so any BOM-cost-saving studies must include the PRM cost too.

48V Direct Conversion Industrial Computing
Industrial computing platforms that already operate from a 48V bus (telecom, automation, robotics controllers) can use the VTM48MP010T135AA0 to deliver 1V at 135A directly to a high-performance SoC without first stepping down to a 12V intermediate. In a 48V-direct architecture, the PRM regulates 48V to a regulated 48V (fixed-output mode) and the VTM then scales to 1V - the system-level efficiency rivals a 12V intermediate design while halving distribution losses in the backplane. Use 48V-compatible Vicor ChiP modules and follow Vicor recommended PCB layout guidelines. Trade-off: requires PCB layout attention to creepage and clearance for 48V at the VTM input side, and the through-hole ChiP does not support pure SMT reflow assembly.

Telecom Base Station Backhaul and Switch Fabric
Telecom base-station backhaul and switch fabrics increasingly need 1V/100A+ rails for advanced DSPs and switch ASICs. The VTM48MP010T135AA0 fits a 48V-distributed backplane where a 48V PRM is the primary isolated output, and the VTM stages point-of-load 1V for the digital cores. The fixed 1:48 transformation ratio produces a 1V nominal output at any load, and the SAC topology rejects 48V bus transients far better than conventional buck converters. Design tip: use Vicor P/N 1323 ChiP thermal interface material on top of the module for sustained 135A operation, and pair with a Vicor IBOA filter module if you need conducted EMI compliance (EN 55022 Class B). Trade-off: requires pre-regulation upstream; the VTM is not a standalone module.

Wichtigste Unterscheidungsmerkmale
- Highest continuous output current in the 1V/1323-ChiP VTM family (vs. VTM48MP010T107AA0)
- ZCS/ZVS Sine Amplitude Converter topology eliminates conventional buck loop-bandwidth limits (vs. Conventional buck converter (e.g., 100A buck POL))
- Factorized Power Architecture allows clean upstream regulation (vs. Single-stage buck at 48V input)
- Pin-compatible variants cover the full 1V POL spectrum (vs. VTM48MP010T107AA0 and VTM48EH010T135AA0)
Designhinweise
The VTM48MP010T135AA0 dissipates approximately 4-7W at full 135A load with 96-97% typical efficiency (Estimated: P_dissipated = V_OUT * I_OUT * (1/efficiency - 1) = 1V * 135A * (1/0.965 - 1) ≈ 4.9W). The ChiP-1323 package has a co-molded thermal interface, so attach a thermal pad or TIM to the top side and provide at least 200 LFM airflow at sustained full current. Multi-layer PCB copper pours reduce the bottom-side thermal resistance but are not a substitute for top-side heat removal at 135A.
Follow Vicor ChiP-1323 PCB layout guidelines strictly. Use multiple PCB layers for high-current +OUT and -OUT planes (recommendation: 2 oz copper, 4 layers minimum). Place VTM input-output sense and gate resistors as close to the package pins as the layout allows. Maintain creepage/clearance for 48V input rated at least 1.5 mm for a typical 80V switch-and-surge requirement. Reference the Vicor evaluation PCB layout for footprint and via patterns.
Do NOT drive the VTM48MP010T135AA0 from a non-Vicor source unless the upstream converter is verified to meet the VTM's input ripple and dynamic response envelope. The SAC topology expects a clean, pre-regulated PRM bus; an upstream buck will fold ripple into the 1V output via the VTM's fixed-ratio transformer action. Also, do NOT exceed 60V at +IN even briefly - the VTM does not have an internal overvoltage clamp. Always size upstream inrush and surge protection for 60V peak.
Keep the VTM-to-PRM interconnect short and use twisted-pair or stripline routing to minimize input leakage inductance. According to the Vicor datasheet, the reflected input ripple of a SAC is the full load current minus the magnetizing current; without proper input bypass (e.g. 100 µF + 10 µF + 0.1 µF input capacitor bank), this ripple may couple back into the PRM and degrade its control loop. Also, the SC pin (pin 5) must be tied to SGND at the load to maintain regulation accuracy.
The 1V/135A rail feeding an AI ASIC or high-end FPGA has very fast current edges, so the system designer should add a small L-C filter (≤20 nH + 100 µF MLCC bank) at the load if the ASIC's voltage tolerance is sub-30 mV. Although Vicor's claim of 2304x output-cap reduction is achievable in their reference designs, real-world board parasitic inductance often necessitates that the system engineer adds back a modest output filter. This is not a defect of the VTM but a side effect of board-level parasitics.
